PE gas pipe

product description   

PE gas pipes have many excellent properties and are used in gas transportation. The corrosion of steel pipes and cast iron pipes and the leakage of joints will be completely solved, thus ensuring the safe operation of the gas pipe network system. PE material used in PE gas pipe is inert material, which can resist the erosion of various chemical media, low friction coefficient of pipe wall, small flow resistance, strong conveying capacity, electric hot-melt connection, higher interface strength than pipe body, high toughness PE fracture Elongation is generally more than 500%, PE gas pipe has good seismic performance, resistance to slow crack growth (SCG), rapid crack propagation (RCP) and flexibility and scratch resistance. PE gas pipe has strong adaptability to uneven settlement of pipe foundation and strong wear resistance. It can adopt a variety of non-excavation methods, which greatly facilitates construction and installation. The system cost is low, maintenance cost is small, and engineering cost can be greatly reduced.

Polyethylene (PE) gas pipelines have been successfully used in gas distribution, with long-term service life, excellent corrosion resistance, reliable connection and safety performance, and low construction and maintenance costs. Many advantages have been favored by the majority of gas companies. According to different raw material grades, polyethylene gas pipes are divided into two grades, PE80 and PE100. According to the standard size ratio, they are divided into two series: SDR11 and SDR17.6. The SDR11 series can be applied to natural gas, liquefied petroleum gas (gaseous) and The distribution and distribution of various gaseous media such as artificial gas, SDR17.6 series is suitable for the distribution of natural gas.

Features   

● Light weight, easy to transport and handle.

●Good flexibility and excellent impact resistance. The pipeline is deformed by external impact without affecting the operation of the pipeline and can be recovered. The flexible pipe can realize the "combination of pipe and soil" to effectively ensure the safety of the pipeline.

●Excellent corrosion resistance. The pipeline is not corroded by external acid and alkali salts. There is no scaling on the inner wall to ensure smooth air flow.

● The connection is safe and reliable. It adopts hot-melt butt or electrofusion connection to form a homogenous connection system with tight connection. Simple construction. The pipe is light in weight, reducing construction labor intensity, effectively shortening the construction period and reducing construction costs.

● Long service life. The normal service life is 50 years.
